4 DPSI-00 Operating Instructions Version.0e Specifications By purchasing the DPSI-00 you acquired a highly progressive electronical product, that was developped and produced in Germany. Developping it, our top priorities were on highest quality, functionality and reliability. Recommodations and requests of worlds best RC-Pilots were considered and taking into account during the development of the product. Optical and technical final inspections at a large scale ensure that you as a customer receive an absolutely reliable product, which will tremendously increase the safety in operation of your RC-model. Naturally, the DPSI-00 went through intensive flight testing, in which all circumstances were taken into consideration. We would recommend to you, to read these directions of use thoroughly and to consider the installation advice. That way many mistakes can be prevented in advance. The DPSI-00 serves as a redundant power supply and distribution for receiver and servos (steer actuators) in RC-models. The redundancy is reached by two connected 5-cell batteries (with 6 volt rated voltage). If one battery fails, the safety in operation is ensured by the second battery. Under normal conditions, both batteries are discharged at the same time. Because the supply voltage turns on electronically (the switch doesn t turn on current, just the start-up signal) no losses, contact failures or transition resistances occur. This internal electrical switch is also highly secure. In this manner, a turned on DPSI-00 stays turned on - even if, for instance, the turn on/off switch is disconnected or interrupted. This way an outstanding security is reached for the turn on/off switching operation already. Intensionally electronical switching from one to the other battery was abstained from, because this would mean a higher risk of operation failure. Both batteries of the DPSI-00 always discharge at the same time. Page 4 of

5 DPSI-00 Operating Instructions Version.0e Thereby a recovery diode voltage drop has to be put up with, but for the DPSI-00, due to the top quality components, this only amounts 0.V (at A) - 0.8V (at 9A). However, the main advantage of the DPSI-00 lies within the possibility, that all connected servos can be supplied with the full power of the battery and that every servo receives the maximum of possible electric current, without putting a strain on the damageable receiver. This way, up to 6 servos (!), resulting from 0 receiver channels, can draw a constant current of together 9A and peak current up to 70 A out of the DPSI-00 - and that with negligible losses! Every servo obtains the full power of the connected batteries. By that means, the maximum floating speed and the highest regulating power of the servos are guaranteed. The receiver is supplied by a regulated, stable voltage of 5.0V from the DPSI-00 (according to the manufacturer, a maximum voltage of 5.V for secure operation of most receivers is permitted). In order to increase security even more, every servo of the DPSI-00 has a highly effective T-filter looped-in into the signal network. This way RF jamming caught by long servo-cables are reduced up to 90%! Ferrite rings, which were used till now, can be omitted; this reduces weight and costs. Furthermore, an interference elimination of the DPSI-00 is considerably more effective than interference elimination by ferrite rings (as demonstrated in the following figures). As a matter of course, with the inserted filters a troublefree operation with the new digital servos is possible also. Page 5 of

7 DPSI-00 Operating Instructions Version.0e In order to supply every servo with optimumly processed control pulses from the receiver, the control pulses are amplified electronically. Normally, the pulse is weakened in case of a parallel connection of the servos (V cable), and therefore becomes more interference-proned. With the DPSI-00 the impulse is preserved completely, even if four servos are connected at one channel (as demonstrated in the chart with 5V supply of the receiver). Servo signal, in case of four servos connected at one receiver output (xv cable) Here the signal has voltage level of merely.6 Volt Signal, if 4 servos are connected to the DPSI-00 (resultant of one receiver output) Here the signal has the orignal voltage level of 4.5 Volt coming from the receiver. Page 7 of

8 DPSI-00 Operating Instructions Version.0e In order to enable an optical switch-control, three light-emitting diodes (LEDs) were built-in the DPSI-00. The first two light-emitting diodes show, whether the particular battery is turned on/connected; the third lightemitting diode signals whether the receiver is supplied with 5V. For the purpose of achieving external monitoring of the batteries, the switchcable of the DPSI-00 contains three LEDs in addition. Both of the outer LEDs are identical with the two LEDs concerning the batteries in the DPSI- 00. The LED in the middle is intended for the control of an additional receiver battery (see also Operation with Lilon-batteries). The DPSI-00 doesn t need to be disconnected from the batteries during longer break periods (for instance during the winter e.g.), because the self-discharge of the batteries is much higher than the current consumption during breaks, which is practically not measurable. Short circuits on the servos stepping line, no matter versus the negative or positive pole of the servo cable, do not lead to the destruction of the DPSI-00. Every other servo on this channel stays fully functional. Even a reverse battery of the servos doesn t damage the DPSI-00. In that fashion, mistakes of use and external influences can not lead to the destruction of the DPSI-00. As a means to increase the safety in operation, the number of piece parts actually involved in the switching operation is intentionally as small as possible. In order to avoid problems originated by piece part failure and any occuring RF emission, the use of a microcontroller was abstained from while developping the DPSI-00. Our philosophy: Sometimes less can be more. In order to be able to connect all commercially available receivers, the DPSI-00 is delivered with different servo cables (to the receiver), depending on the specific demand. Normally, gold-plated JR-contacts are used. Page 8 of

9 DPSI-00 Operating Instructions Version.0e Notice for the application of Lilon-batteries Many competition pilots insert Lilon-batteries in their models (former: Duralite). These batteries have a rated voltage of 6V and while being very lightweight, they have an extremly high capacity. The disadvantage of these storage batteries lies within their high internal resistance. As a result, there is a risk, that if high amounts of current are drawn from the batteries, the voltage can drop dramatically. In case of a high servo load, it is quite possible, that the rated voltage drops down to.8v (for instance after a couple of snap figures). Such a drop indeed only lasts app. 0.5 to second, but as a consequence, the receiver has too little voltage during that time period (app.. to.4v) and therefore fails during that short time. In order to avoid that risk, the DPSI-00 enables for the receiver to be supplied by a third (stand-by) battery. This battery should be one with a rated voltage of 6V also. The nowadays smallest obtainable capacity of 800mA suffices completely, because a regular receiver without connected servo consumes only 8-5mA. The spare battery is discharged only, if the voltage of the main batteries drops below app. 5V. For the purpose of showing the presence of that battery, there is a third light-emitting diode (in the middle) placed in the switch-cable, which lights, when the battery is connected (and the DPSI-00 is turned on). This stand-by battery does not need an additional switch, because it is also turned on by the main switch. Notice for the use of a second receiver: The DPSI-00 permits the connection of a second receiver. Since this is required by some organizations (for instance the big model meeting in France), the DPSI-00 is usable in this case too. This second receiver is supplied with 5V by the servo cables also. Both receivers should be of the identical type (f.i. both JR SMC-0). All these proceedings allow a maximum of operation security combined with the maximum possible performance. Page 9 of

10 DPSI-00 Operating Instructions Version.0e Assemblage of the DPSI-00 The easiest way is to glue the receiver directly on or under the DPSI-00 with double-sided gluey cellular rubber (5-0mm thick). Because the DPSI- 00 is mostly used in big models, it makes sense to fasten the complete package (DPSI-00 with receiver) with four small rubber rings freeswinging towards four sides in the fuselage as demonstrated in the chart.

11 DPSI-00 Operating Instructions Version.0e Also a bedding on four silicon-hose pieces is well tried. Thereto the complete package is fastened vibration reduced on four elevated piles (as demonstrated in the chart). Alternative fastening Screws fitting in tube DPSI-00 Latex foam rubber Silicon fuel tubing Receiver Mounting panel in the fuselage Naturally, a fastening on thick cellular rubber is also possible. In general it is important to pay attention to an as free-swinging fastening as possible. This applies especially to the receiver, as it is far more susceptible to vibrations than the DPSI-00. In case of very high amounts of current (many servos) and under competitive conditions, the top surface of the DPSI-00 (screen printing foil) should remain free to enable the carrying-off of heat. Page of

12 DPSI-00 Operating Instructions Version.0e Connecting the switch Mechanical switches involve the risk of failure. The vibrations at the fuselage wall of big models are quite high. Therefore failures of f.i. flip switches are seen quite often. In order to exclude any mechanical influence on a switch, the DPSI-00 uses a pin to turn on/off the receiving station. It is a mm gold-plated plug pin, which, if set into the on jack (red), turns on the DPSI-00 and if set into the off jack (blue) turns it off. Even if the pin should get lost during a flight (which does hardly seem possible due to the strong mainstay), the DPSI-00 stays turned on. The DPSI-00 can only be turned off, if the pin is set into the off jack. Of course one mustn t set a pin into both jacks, even though that doesn t damage the DPSI- 00. If that was the case, the DPSI-00 would stay turned off while the batteries would discharge slowly with approximately ma. During onperiod conditions the pin should always remain in the on jack. If the pin should get lost, you can make do with a mm wire or a mm screw, which can be set into the respective pin jack. Off jack On jack The on/off switch can be placed anywhere (for instance at a fuselage sidewall). The labeled cable S is connected to the pin-plug labeled with S. The orange wire of the cable points towards the top surface and the brown wire points towards the lower side of the DPSI-00. Page of

13 S DPSI-00 Operating Instructions Version.0e The second cable is responsible for the light-emitting diodes within the switch. It is connected to the plug labeled as L. Here the orange cable is turned upwards and the brown cable downwards as well. This cable can be omitted, if you want to do without the (external) LED display.

14 DPSI-00 Operating Instructions Version.0e If the optical control with these LEDs doesn t suffice, also commercially available voltage indicators for the batteries (for instance JR Voltspy, JR NC-Akku-Controller 4/7) can be connected. With these, the exact voltage of the particular connected battery is controlable (please pay attention to the fact, that these potential indicators for the batteries are tuned at 5 cells). In order to connect these devices, a V cable is needed, which can be very easily made by oneself (as demonstrated in the chart): DPSI-00 connector C free free Connect with Connect with Connect with To battery monitor To battery monitor Page 4 of

15 DPSI-00 Operating Instructions Version.0e Connecting the receiver While connecting the receiver, not every one of the 0 inputs of the DPSI- 00 has to be connected. This way, receivers with less than 0 channels can be connected to the DPSI-00, too. Every cable that leads to the receiver, can supply the receiver with 5V - due to that it does not matter, which cable is plugged in.

16 DPSI-00 Operating Instructions Version.0e Free receiver cables of the DPSI-00 The DPSI-00 has 0 connecting cables which are usually plugged into the receiver. If not all of these cables are used (like if the receiver has less exits), these free cables must not be plugged into the servo exits of the DPSI-00 UNDER NO CIRCUMSTANCES! This can lead to the destruction of the drive circuit. Free cables can rather be insulated with electrician s tape and be fastend somewhere (for instance with a cable tie at the rubber rings, the DPSI- 00 is fastened at). Free receiver cables of the DPSI-00 when using JR-receiver Several Graupner/JR receiver have an own plug labeled as Batt. which is normally used to connect the battery. (for instance Servo to 9 and Batt. ) THIS PLUG (Batt.) MUST NOT BE USED! Even if it would seem neat to stow away the tenth cable of the DPSI-00 this way, it MUST NOT be connected there at any case! (see also the corresponding chart). The consequence would be strong movements of all servos, that could also lead to damages at the servos or the mechanism. Usually, this applies to other receivers as well, except, if the plug Batt. positively permits the operation of an additional servo (please read the directions of use of the receiver, whether this is the case). Using two receivers It is also possible to use two receivers. The particulary designated DPSIservo cables are connected to the receiver they are needed at. In case of operation with two receivers, servos should not be connected directly to the receivers (limited current). Page 6 of

18 DPSI-00 Operating Instructions Version.0e Connecting the batteries Commercially available batteries with a rated voltage of 6V can be used (for instance 5 cell NiCd or NiMH storage batteries, but also 6V lead batteries (where they are necessary) or LiIon batteries). The rated voltage of the batteries mustn t be higher than 6V (fast loading NiCd sometimes have momentarily up to 8V after charging, this is naturally permitted) and please take care, that the current the batteries can possibly deliver suffices for the number of connected servos. Use of 4-cell NiCd batteries In general, the operation with only 4 NiCd cells is possible (4.8V rated voltage). In this case a small 6V battery (preferably a 800mAh LiIon battery or, respectively a battery, whose voltage is not higher than up to 6.4V after charging) should be used to supply the receiver (see also Remarks on using LiIon batteries ). This is necessary, so that the receiver is operated with rated voltage. Due to the slight voltage drop within the DPSI-00 the voltage at the receiver with just four NiCd cells amounts to approximately 4.40V (if the total load of the DPSI-00 sums up to 0A) respectively 4.48V ( if the load is 5A). In case of doubt it should be controlled in which voltage range the receiver can be operated. If secure operation is possible till app..8v, an additional receiver battery is not necessary. Page 8 of

19 DPSI-00 Operating Instructions Version.0e Battery capacity In general the possible current load and the capacity of the used batteries should be observed. For example, storage batteries with 450mAh are way to small for a T.O.C.-Model with 6 servos. In this case, at least two 400s that can be discharged with 0C should be used. (C is the rating of storage battery in Ah => this means an battery with.4ah can at 0C be loaded with 0*,4A= 4A ). Especially when using digital servos, a raised current consumption has to be expected. On an average, a T.O.C.- Model with digital servos draws approximately.6ah to.ah during 0 minutes flight time. The dimensioning of the batteries should be proceeded carfully! In cases of doubt please ask the model manufacturer. When chosing the right battery, keep an eye on the fact, that the connecting cables of the batteries are thick enough. If an battery with a 0.5mm square mil is used, the advantage of the DPSI-00 comes close to nothing, because losses origin in the thin cable. Thereto the following calculation: A highly flexible Cu-cable with 0.5mm square mil and of approximately 5cm length has a resistance (back and forth) of app. 0.05Ohm. The power handling capacity of such a cable amounts at most.5a. Assuming a current of 0A, the voltage drop in this cable already comes to 0.5V. Instead of the 6V only 5.5V arrive at the DPSI-00! By that means, for example battery cables for T.O.C.-Models should at least have a square mil of.0 to.5mm. The battery connecting cable should be soldered up with the delivered green Multiplex high current connectors, in order to be compatible with the DPSI-00. A heatshrinkable tube to insulate the soldered joint ususally comes along with the delivery also. If the batteries are placed far away from the DPSI-00 (so that the connected cables are quite long), it would make sense to twist the cables of the batteries. Page 9 of

Page 0 of

21 DPSI-00 Operating Instructions Version.0e Due to the special construction, the DPSI-00 does not have a reverse battery protection! Thus, please pay attention, that the batteries are always connected correctly. This means, that the red cable is always on plus and the black cable is always on minus. Please verify this rather too many than too few times! The DPSI-00 switches battery Plus, this means both batteries are, if they are connected to the DPSI-00, interconnected with Minus (Ground). If every battery should be connected by a V-cable, (which would make charging of this connected battery possible, if it is connected to the DPSI- 00 at the same time), then it should be observed, how the battery charger works, when both batteries ought to be charged at the same time. In this manner it makes generally sense and is safer, if the batteries are disconnected from the DPSI-00 while charging. If the green Multiplex high current connectors are used that came along with the delivery, it should be no problem, to quickly disconnect the batteries in order to charge them. The gold-plated contacts enable a secure connection even after many plug-ins and outs. That way, also the additional weight of the V- cable is saved as well as the work of making them. In order to meet the demand of many pilots to configure their system according to their individual needs, the Multiplex connectors were not soldered up with the cables of the DPSI-00. This way, you can accomodate the cable length according to your needs. Please pay attention, that the jack is soldered up with the battery cable and that the plug is soldered up with the DPSI-00 cable. Please do not omit, to put the heat-shrinkable sleeve over cable ends before soldering. Please work carefully and pay attention to the polarity of the cables. Notice: If NiCd batteries are charged quickly, they usually have a much higher voltage then if charged regularily. When turning on directly after charging, it is possible, that the used servos tremble. If that should be the case, it is better to wait with flying for 5 minutes after quick-charging, till the voltage state of the batteries is halfway normal again. Page of

22 DPSI-00 Operating Instructions Version.0e Remarks on using LiIon batteries On demand of many competition pilots, the DPSI-00 was extended by one function, that permits the use of Lilon batteries (former: Duralite). Because these batteries can, due to their high internal resistance, momentarily drop down to.8v voltage on high current loads, the receiver would have unsufficient supply during that time and would fail. The model would be uncontrollable during that short period of time. For that reason, an additional battery for the receiver can be connected to the DPSI-00. It has to be an battery with 6V rated voltage also. A capacity of 500mAh suffices though. The presence of this additional battery is signaled by the middle LED within the switch. If this LED is lighted, the battery is connected and the DPSI-00 turned on. This way, external control is possible at any time. If all three LEDs are lighted, all batteries are plugged in and the DPSI-00 is turned on. The additional battery is only discharged by the receiver, if the voltage of the main batteries drops down below app. 5V. Continuous discharging only takes place by the current consumption of the LED in the switch (app. 0mA). A 500mAh battery would be sufficent for app. 5 hours of use, if its function is needed (and no servos are connected directly to the receiver). On principle, it is possible to remove the contact pin from the switch after turning the DPSI-00 on, because the DPSI-00 stays turned on (selflocking), as already mentioned before. If you use batteries with high internal resistance (LiIon), the pin has to remain set into the jack at any case! If the input voltage of the DPSI-00 drops below.6v, the latch does not work any more (only the external switch). It is possible, that the voltage of Lilon batteries drops down to these.6v! Page of

24 DPSI-00 Operating Instructions Version.0e Connecting the servos The DPSI-00 distributes the 0 servo exits of the receiver at altogether 6 servo connections. Here a distribution was chosen, that makes a big number of combinations possible. This example shows the connected servos from a T.O.C.-model with the use of a JR radio control. Naturally you can adapt the servo distribution as well as the receiver distribution to your special needs and ideas.

All servos have the pulse cable upwards (as indicated on the sticker). It is recommended, to plug in all servos directly at the DPSI-00. That way the operation security is increased and all servos receive the full energy. If two or more servos are soldered directly in the corresponding rudder and are guided with one cable to the DPSI-00, this cable has to carry the current of both servos which can lead to voltage losses. Page 4 of

25 DPSI-00 Operating Instructions Version.0e It is recommended to connect every single servo within the model to the DPSI-00 in order to receive to full interference results. Should nevertheless one or two servos be plugged in directly at the receiver, the maximum possible current load should be payed attention to. Because the receiver is supplied with stable voltage out from the DPSI- 00, which is drawn from a voltage regulator, the amount of drawable current is limited to A! We therefore recommend, not to connect a servo directly to the receiver. Higher current loads could, due to resulting losses, in worst case actuate the overtemperature protection of the voltage regulator. If that was the case, the receiver would be no longer supplied and that would inevitably lead to a crash of the model! Security of the cables connected to the servo Some pilots have some misgivings, that the servo cables connected to the DPSI-00 might whip and therefore lead to a failure. Up to this day nothing like this has been observed (even with strong vibrations). Yet, to be on the safe side, every connected servo cable can be secured to the upper and/or lower board by a drop of hot-melt adhesive.this is well-tried in practice, too. Also, this connection is unproblematically detachable. Page 5 of

26 DPSI-00 Operating Instructions Version.0e Operation To turn on the DPSI-00, the mm plug pin is taken out of the off jack (blue) and set into the on jack (red). If all batteries are connected and charged, the three LEDs of the DPSI-00 board are lighted (and also the two outer LEDs within the switch, if connected). This way, operation is signaled. If only one LED is lighted, then maybe one battery is not connected. The orange wires of all cables always have to be topside! To turn off the DPSI-00, the plug pin is placed into the blue off jack. Should the plug pin get lost, you can also make do with a mm steel wire or a mm screw to turn on/off the DPSI-00. If you use an additional receiver battery (for instance if using LiIon cells), it has to be disconnected from the DPSI-00 while charging at any rate! While charging the main batteries, it is recommended to disconnect these also from the DPSI-00. Simultaneous charging of connected batteries is possible in theory, but it can lead to malfunctions of automatic battery chargers. Page 6 of

27 DPSI-00 Operating Instructions Version.0e * Security advice In general, all connecting cables should be wired in a manner, that they do not come into contact with moving or hot parts of the model (like servos, gears or exhaust pipes). * The DPSI-00 has to be protected against humidity and wetness. * * * * * * * * Inexpert handling of the DPSI-00 can lead to serious damage/hurt of equipment and/or people! Generally, in advance of every operation, check all connections within your model! All plugs have to be correctly polarized and thouroughly contacted (firmly set in). Loose cables carry a high potenial risk of danger! In no case it is allowed to use sources of current which exceed the declared voltages! Preferably use 5 cell NiCd batteries. The current-carrying contacts of the connecting plugs must not be shortcircuited. In this manner, the short-circuited cables can be heavily heated and even melt. Under no circumstances, the DPSI-00 is to be taken apart or technically changed. There are no components within the DPSI-00 that could be repaired or maintained by the purchaser. Do not use the DPSI-00 other than for purposes in recreational RCmodel making. Especially the use within machines that transport or carry people is strictly forbidden. Operate the DPSI-00 exclusively with radiocontrol components intended for RC model making. Pay attention to the fact, that the batteries are fully charged. Empty batteries inevitably lead to outage of the RC components and therefore to the crash of the model. Page 7 of

28 DPSI-00 Operating Instructions Version.0e * * Do not expose the DPSI-00 to extremly hot or cool temperatures, wetness or humidity.

31 DPSI-00 Operating Instructions Version.0e Further remarks Operation of the DPSI-00 with gyros It is possible to operate the DPSI-00 with gyroscopes. Then it has to be taken care, that the servo(s) is/are not connected to the gyroscope but, as described before, directly to the DPSI-00. The gyroscope is rather looped-in between DPSI-00 and the receiver. This way, the gyroscope is operated constantly with 5V. Example: The gyroscope (for example Fuzzy Airplane Gyro) is to be connected to the channels and 5 of the receiver (for the ailerons). Thereto the gyroscope is, like usually, connected directly to the receiver (channel and 5). The cables, that normally lead from the DPSI-00 to the receiver, are now connected to the servo exits (plugs) of the gyroscope. The Servos are connected to the DPSI-00 as usual. In general, it is important, that the power supply of the gyroscope is looped trough : from the receiver exit to the servo exit (maybe measure with mulitmeter => 0 from Positive to Positive and from Negative to Negative). This usually is the case. Page of
